That only works once an app is far enough along in the launch process that it's able to run javascript. We need to give apps a high priority before then. Is gaia currently setting the "visibility flag" on <iframes> of launching apps right away? If not, we should make that happen. Then we should look at the the visibility flag very early in the forking process. But we don't have to monitor it aggressively throughout the startup of an app as it's unlikely to change. / Jonas _______________________________________________ dev-b2g mailing list dev-b2g@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-b2g
